chrisd Posted September 21, 2002 Share Posted September 21, 2002 I failed to get on the track at Castle Combe today (103dB - 109dB with their suggested muffler!!) How, or where, do I re-pack the silencer with wadding as it seems to be lacking padding? Any suggestions?? As a result of said failure, I ended up at Silverstone to watch the historic racing. Plenty of other 7's and a good atmosphere too, so not a total disaster Chris Link to comment Share on other sites More sharing options...
Trevor Phillips Posted September 22, 2002 Share Posted September 22, 2002 I've just fitted a Custom Chrome Sound Barrier 8" exhaust behind the main one. It is adjustable and when closed drops the VX engine by 5db [and a lot of HP]. Fitted so I can get through SVA with an ex-Caterham Vauxhall Challenge car. We failed with a standard exhaust at 103bd at 4850rpm. Need to meet 103db. Link to comment Share on other sites More sharing options...
R500 CYA Posted September 22, 2002 Share Posted September 22, 2002 I have repacked a techcraft silencer recently for a Goodwood quiet day and reduced the noise by 5dB! It's a simple enough job if you have a repackable system (sounds obvious I know). Simply open up the silencer at the exhaust end, gasp in amazement that there appears to be nothing inside at all except a few black bits of old loft installation, and refill with exhaust wadding (£35 a box from DT) making sure you wear gloves (and long trousers I later discovered) as it itches like hell. Instant result and no power loss! If you have a non repackable silencer, I think you're probably screwed! Nick Link to comment Share on other sites More sharing options...
peterg Posted September 23, 2002 Share Posted September 23, 2002 www.techcraft.co.uk sell a bag of Basalt wadding for £27 😬 Link to comment Share on other sites More sharing options...
